I've just started a Klingon Tac, and I'm unsure which ship(s) to use for fastest leveling up.

I've played around a bit with the starting Norgh, and while being awesome on the offense after coming out of battle cloak, it's also paper thin. Can't stay and slug it out with more than a couple of frigs without risking death.

So, should I invest my ship requisition point in a K't'inga or a Qorgh? or stay with the Norgh?

Also, in the long run, which path is fastest for leveling up a tac (BoPs, raptors or battle cruisers)?

Um enjoy what little of it that there is? Get a few different ships so that at end game your not....OMG I"VE ONLY EVAH USED ONE SHIP WTF!!!!!!

They're all pretty good options. Especially once you get alpha. Whenever that happens again I've forgetton. Alpha is a very long buff it works great on the constant pew pew pew that cruisers lay down. Seriously its 30 seconds. Use that with DEM and see what comes out ahead vs 3 mobs.

Seriously relax have fun. Try out some new stuff. Espcecially if you've NEVER flown KDF cruisers they are NOT like Fed cruisers. KDF cruisers are like....slightly chubby engineering heavy escorts. Anyways tryout a few things while you have the chance.
